This thesis addresses the issue of GPS satellite spoofing using affordable hardware. The approach involves capturing I/Q-samples from GPS-signals and employing a phase interferometry algorithm for direction finding. By determining the direction of a satellite at a given time and comparing this with decoded navigation messages that reveal the satellite's actual location. This method is able to verify the authenticity of the satellite signals where a discrepancy between these locations suggests potential spoofing. Although the project's theoretical contributions are significant, the practical outcomes fell short of the initial ambitions due to various constraints encountered during the study. Nonetheless, the findings provide valuable insights into the detection of GPS spoofing, highlighting both the potential and the limitations of the proposed method within the allotted timeframe.
